So, where’s the truth? Should you warm up your engine? Is there a point in waiting till the temperature gauge starts reacting? In this short video, I will tell you everything I know about this and the effects this will have on your engine.
Engine warm-up is a serious thing that can easily kill any modern engine if overlooked. But a lot of us just do this the wrong way, so we hurt our engines which in turn hurts our budgets.
I hope this video is helpful and will enhance your knowledge about how modern cars work. Subscribe to the channel and get updated on new videos I publish!

Local quarry operation had two Caterpillar bulldozers. One driver started his engine then for 15 minutes carried out the daily lube routine. The other driver started up and immediately went to work, carrying out the lube routine at the end of the day. This Bulldozer had two replacement engines over the years whilst the other is still running with the original engine!

In Australia when you turn your car on? Its already warmed up.

You need not 'warm up' a modern engine. But do not use full throttle until the temp gauge reads in the normal range

Absolutely correct. Warm up period should be no longer than 60 seconds, this allows the settled oil to circulate to the components that need it and provides for proper cooling of the internals that can potentially warp if the temperature difference is dramatic.

Any car since the 1980's needs 10 seconds max. Drive it easy at first depending on terrain and outdoor temperature. The car warms up as you drive it. Idling is not good for any car.

The best way to warm your engine is to drive it. Of course you should not push it hard for the first few minutes and in fact the transmission will take even longer to achieve the optimum temperature but nothing will happen if you are parked in your driveway. Oil pressure builds up in the time it takes to put the car in drive and release the park brake. Long engine life depends on correct running in (which is not babying it) and regular oil and filter changes.

One exception to driving away cold: Tickover is automatically increased to say 1,000 rpm, so when you have to negotiate a steep snow-covered downhill slope immediately where the lowest possible gearing is the best option, you can lose traction. Sure, get off the brakes when the tyres have locked up, but that may not be enough. Worse case is you go through 180 degrees, but at least you can go down in reverse. You are unlikely to meet anyone coming up as no one else would be deranged enough to tackle 40cm of fresh snow. Jack, the Japan Alps Brit

I would immediately stop an engine with low oil pressure at start-up. That is a recipe for disaster. Indeed, the "Idiot Light" safe oil pressure indicator tells you damage may occur. Look at all the small. e.g. lawnmower, engines with automatic oil pressure related shut down. This should tell you some thing, and not necessarily that the oil level is low.
